All along the coastal states in the US, fishing rules and regulations vary in each state. Bag limits and size limits differ from state to state for no apparent reason. It is confusing at best, and the differences usually go unnoticed unless you live close to a border and fish in both states. If you are one of those anglers, these rules can seem ridiculous in some instances.
Escapement
This is the key term biologists use in fish conservation. It relates to the number expressed in a percentage of fish that make it through all they have to deal with to spawn and produce more fish. They escape things like being eaten by another predator fish, natural mortality, and of course, our hooks and lures.
Optimum Yield
As defined by the Atlantic States Marine Fisheries Commission (ASMFC), optimum Yield (OY) is defined as the amount of harvest that could be taken while maintaining the spawning stock biomass per recruit level at or above 30% of the level that would result if fishing mortality was zero. In this case the 30% is for the red drum fishery.
Escapement rate targets can and will vary by species. The target rates are set based on harvest results, sampling, and surveys. In species that have a heavy harvest rate, the escapement rate target may be raised in order to insure more spawning fish for the next year. That raise in escapement rate necessarily means among other things a decrease in bag limits, size limits, or both f or a given species.
Bag and Size Limits
Biologists tell us that they can achieve their desired escapement rate in more than one way. They can allow us to take more but smaller fish or allow us to take fewer but larger fish. They really dont care which option as long as the rate is accomplished. So, they hold forums and meetings around the state to hear what the anglers want to take more small fish or bigger but fewer fish. They do what the public wants.
The Dilemma
The problem that border fishermen see is where the two border states have chosen opposite options in their bag and size limits. It is hard to conceive how one state allows, as an example, a 15 fish bag limit and 13 inch size limit on seatrout when right across a river the bag limit is 5 fish and the size limit is fifteen inches. But, the answer is in how the states anglers voted at the various forums.
Bag and size limits are different for the same species of fish in literally every state. That means if you fish a border are between say North Carolina and Virginia, or between Mississippi and Louisiana, you need to be aware of the differences.
The Sticky Solution
Although many of you will send me email about this, there is a solution to the border problem. That solution is to buy a license for both states! There is a pitfall to this solution, however. If you launch in one state and fish in the other, you are going to have to abide by the rules of the state from which you launched. No game warden is going to allow you to have over the limit simply because you have another states license in your possession. Its sticky at best, and my advice is to simply follow the rules of your own state. If you want to fish the other states waters because the limits are more liberal, go over and launch in that state. That will keep you out of trouble!
